Subject: test/nilptr: add more tests
X-Git-Tag: go1.2rc2~341

test/nilptr: add more tests

These tests were suggested in golang.org/issue/6080.
They were fixed as part of the new nil pointer checks
that I added a few weeks ago.

Recording the tests as part of marking the issue closed.

Fixes #6080.
